Extract

Kodoskops parasti satur lielu kasti, kurā atrodas lampa un ventilātors, kas to dzesē. Kastes augšā atrodas fresnela lēca, kura fokusē gaismu. Uz šīs lēcas novieto caurspīdīgu plēvi ar tekstu vai attēlu, šai plēvei gaisma spīdot cauri nonāk uz spoguļa un lēcas kas parasti atrodas kājas galā, virs fresnela lēcas. Šī lēca un spogulis fokusē attēlu un projecē to uz vajadzīgās virsmas.
